Usage and Applications of Magnetic Latching Relays

Usage of magnetic latching relay

1. Expand the scope of control

For example, when the control signal of a multi-contact relay reaches a certain value, multiple circuits can be connected, disconnected, and connected at the same time according to different forms of contact groups.

2. Zoom in

For example, sensitive relays, intermediate relays, etc., only need a small amount of control to control high-power circuits.

3. Integrated signal

For example, when multiple control signals are input into a multi-winding relay in a prescribed form, the predetermined control effect can be achieved after comparison and synthesis.

4. Automatic, remote control, monitoring

For example, relays on automatic devices and relays on other electrical appliances can form a program control circuit to realize automatic operation.

Applications of magnetic latching relay

As a kind of bistable relay, magnetic latching relay has been widely used due to its advantages of low power consumption, small size and large load capacity. It is mainly used in the following areas:

1. Smart meters: IC card meters, prepaid meters, single-phase meters, three-phase meters;

2. Reactive power compensation: synchronous switch, composite switch, smart capacitor;

3. Intelligent control: smart home, solar street light control, automation equipment, etc.!
